You'll have no clue if you'll be dry as a bone or sopping wet.
I was sopping wet for months, so this is a worst case plan.
1) Get a pack of Depends pants.
2) Get a pack of Depends Guards.
If things are headed to sopping, first days, try the Depends pant with a Guard inside. You can (gently) change out the Guard during the day as needed, so long as you don't rip up the lining. (Tena pants tear up too easily to use this way). They (Depends Guards) are easier to change and cost less than the pants. The pant offers the extreme backup if you blow out the pad.
Once you get down to a few pads without blow outs, go to the Depend Guard in jockey shots.
As you have fewer issues, you may be able to move to a Tena Men's Guard. They are lighter, less bulk.
I've got to go find a writeup I did years ago.
Warning - cheaper is not better. The "generic" pants (Kroger, Safeway, Walmart, Walgreens) are bulkier, make noise, and are uncomfortable.
All that based on six very soggy months on the pant/pad combo.
